Keeping significant amounts of memory free just-in-case seems pointless. Keeping *virtual* memory free (in other words, reserving swap space) to make sure that root can start more processes may make sense. Providing resident set limits and guarantees to make sure that new root processes can run if they want to even under memory load makes sense. But simply keeping physical memory free doesn't seem to be a good idea: it's just too high a price for things we can achieve using different means.
